Abstract
Método para la purificación de ácido fosfórico después de la extracción mediante disolvente. Brevemente, de acuerdo con la invención, se ha descubierto que las cantidades residuales de portador orgánico se pueden eliminar del ácido fosfórico con un absorbente que absorbe el portador orgánico y a continuación es separado del ácido fosfórico. El absorbente puede adoptar la forma, por ejemplo, de una torta de filtrado a través de la cual se hace pasar el ácido fosfórico que contiene el portador orgánico residual. Se ha descubierto que la utilización de un absorbente adecuado puede reducir la cantidad de portador orgánico residual en el ácido fosfórico después de la recuperación de uranio por extracción de disolvente a menos de 1% de su valor previo a la absorción.
